Rockets and Feathers Revisited: an International Comparison on European Gasoline Markets

This paper re-examines the issue of asymmetries in the transmission of shocks to crude oil prices onto the retail price of gasoline. Relative to the previous literature, the distinguishing features of the present paper are - i) use of updated and comparable data to carry out an international comparison of gasoline markets; ii) two-stage modeling of the transmission of oil price shocks to gasoline prices (first refinery stage and second distribution stage), in order to assess possible asymmetries at either one or both stages; iii) use of asymmetric error correction models to distinguish between asymmetries that arise from short-run deviations in input prices and from the speed at which the gasoline price reverts to its long-run level; iv) explicit, possibly asymmetric, role of the exchange rate, as crude oil is paid for in dollars whereas gasoline sells for different sums of national currencies; v) bootstrapping of F tests of asymmetries, in order to overcome the lowpower problem of conventional testing procedures. In contrast to several previous findings, the results generally point to widespread differences in both adjustment speeds and short-run responses when input prices rise or fall.

Richer and Cleaner? A Study on Carbon Dioxide Emissions in Developing Countries

Sole structures for articles of footwear, including athletic footwear, include a sole structure having a relatively soft and lightweight foam midsole component partially covered by at least one more rigid and/or dense cage (protective) component(s) and/or other protective component(s). The sole structures may include a first portion configured to support at least a heel and midfoot area of a wearers foot, and an exposed outer edge of this first portion may include a billows structure that extends continuously from a medical midfoot or forefoot area of the sole structure to a lateral midfoot or forefoot area. This billows structure may include fewer than five billow outer ridges connected by billow interstitial areas located between adjacent billow outer ridges. Billow thickness at a rear end of the first portion may be larger than the thickness at a front end of the first portion.

How fast are small tourism countries growing? Evidence from the data for 1980-2003.

This paper analyses the empirical relationship between growth, country size and tourism specialization by using a data set covering the period 1980–2003. It finds that tourism countries are small and grow significantly faster than all the other subgroups considered in the analysis. Tourism appears to be an independent determining factor for growth: controlling for initial per capita income and for trade openness does not weaken the positive correlation between tourism specialization and growth. Another finding of the paper is that small states are fast growing only when they are highly specialized in tourism. In contrast with some previous conclusions in the literature, smallness per se is not good for growth.

Why Are Tourism Countries Small and Fast-Growing?

International tourism is today one of the most important tradable sectors, with expenditure on tourist goods and services representing some 8% of total world export receipts and 5% of world GDP. Cross-country data for 1985-95 on tourism specialisation and economic growth reveal the following regularities - (i) many tourism countries have grown faster compared to the other countries; and (ii) they are small. We use a two-sector endogenous growth model to obtain explanatory hypotheses about these two findings. In particular, we define the conditions required for small countries to specialise in tourism and to enter the faster growth path. Our suggestion is that what matters is a countrys relative endowment of the natural resource, rather than its absolute size.

On the Robustness of Robustness Checks of the Environmental Kuznets Curve

Since its first inception in the debate on the relationship between environment and growth in 1992, the Environmental Kuznets Curve has been subject of continuous and intense scrutiny. The literature can be roughly divided in two historical phases. Initially, after the seminal contributions, additional work aimed to extend the investigation to new pollutants and to verify the existence of an inverted-U shape as well as assessing the value of the turning point. The following phase focused instead on the robustness of the empirical relationship, particularly with respect to the omission of relevant explanatory variables other than GDP, alternative datasets, functional forms, and grouping of the countries examined. The most recent line of investigation criticizes the Environmental Kuznets Curve on more fundamental grounds, in that it stresses the lack of sufficient statistical testing of the empirical relationship and questions the very existence of the notion of Environmental Kuznets Curve. Attention is in particular drawn on the stationarity properties of the series involved – per capita emissions or concentrations and per capita GDP – and, in case of presence of unit roots, on the cointegration property that must be present for the Environmental Kuznets Curve to be a well-defined concept. Only at that point can the researcher ask whether the long-run relationship exhibits an inverted-U pattern. On the basis of panel integration and cointegration tests for sulphur, Stern (2002, 2003) and Perman and Stern (1999, 2003) have presented evidence and forcefully stated that the Environmental Kuznets Curve does not exist. In this paper we ask whether similar strong conclusions can be arrived at when carrying out tests of fractional panel integration and cointegration. As an example we use the controversial case of carbon dioxide emissions. The results show that more EKCs come back into life relative to traditional integration/cointegration tests. However, we confirm that the EKC remains a fragile concept.

Benchmarking in Tourism Destination, Keeping in Mind the Sustainable Paradigm

Tourism destination benchmarking and the assessment of tourism management performances are a crucial and challenging task in the direction of evaluating tourism sustainability and reshaping tourism activities. However, assessing tourism management efficiency per se may not provide enough information concerning long-term performances, which is what sustainability is about. Natural resources management should therefore be included in the analysis to provide a more exhaustive picture of long-run sustainable efficiency and tourism performances. Indeed, while the environmental endowment of a site is a key feature in tourism destination comparison, what really matters is its effective management. Therefore, in this paper we assess and compare tourism destinations, not only in terms of tourism services supply, but also in terms of the performance of environmental management. The proposed efficiency assessment procedure is based on Data Envelopment Analysis (DEA). DEA is a methodology for evaluating the relative efficiency when facing multiple input and output. Although the methodology is extremely versatile, for the sake of exemplification, in this paper it is applied to the valuation of sustainable tourism management of the twenty Italian regions.

The economics of tourism and sustainable development.

Although economics has increasingly become a technical subject, this accessible book aims to present important economics results and relate them explicitly to the policy debate. Using a coherent analytical framework, this unique approach offers prescriptions for moving tourism, and economic development more generally, closer to a sustainable ideal. The authors begin by studying the macroeconomic effect of tourism in terms of growth performance and sources of growth. They also examine how the tourism–growth link is affected by the role of imports in the economy, and how tourism impacts upon land use. Further chapters investigate the important issue of forecasting visitor numbers and explore the need for a comprehensive accounting framework to take account of ecologically sustainable tourism. The authors also examine the microeconomic aspects of sustainable tourism and analyse the increasing popularity of environmentally friendly holidays.

Using data envelopment analysis to evaluate environmentally conscious tourism management.

This paper discusses a methodology to assess the performances of tourism management of local governments when economic and environmental aspects are considered as equally relevant. In particular, the focus is on the comparison and efficiency assessment of Italian municipalities located on the costal areas. In order to assess the efficiency status of the considered management units, Data Envelopment Analysis (DEA), a methodology for evaluating the relative efficiency of decision making units, is applied. The efficiency index measure used in DEA analysis accounts for both environmental and economic features correlated to the tourism industry. Further, potential managerial improvements for those areas resulting far from the efficiency frontier can be investigated.

How fast are small tourist countries growing? The 1980-2003 evidence

We analyze the empirical relationship between growth, country size and tourism specialization by using a dataset covering the period 1980-2003. We find that tourism countries grow significantly faster than all the other sub-groups considered in our analysis. Tourism appears to be an independent determining factor for growth, and the reason for that is neither because they are poorer than the average, nor because they are very open to trade. Another finding of our paper is that small states are fast growing only when are highly specialized in tourism. In contrast with some previous conclusions in the literature, smallness per se is not good for growth.

How Consistent are Alternative Short-Term Climate Policies with Long-Term Goals?

Choosing long-term goals is a key issue in the climate policy agenda. Targets should be easily measurable and feasible, but also effective in damage control. Once goals are set globally, given the uncertainty affecting long-term strategies and region-specific preferences for different policy instruments, policies will be better represented by a diversified portfolio to be revised over time, rather than “once and forever” decisions. It therefore becomes crucial to understand to what extent different strategies (or policy portfolios) are consistent with long-term targets, that is, when they imply emission paths which do not irreversibly diverge from globally set goals. The present paper aims to investigate emission paths implied by plausible policy scenarios against those derived by imposing alternative long-term targets, comparing, for example, differences in peak periods. Plausible policy scenarios are for instance Kyoto-type targets with or without participation by the U.S. and/or by developing countries. Different long-term targets considered focus on stabilisation of CO2 concentrations, radiative forcing and the increase in atmospheric temperature relative to pre-industrial levels. In order to account for the uncertainty surrounding the climate cycle, for each long-term goal multiple paths of emission - the most probable, the optimistic and the pessimistic ones - are considered in the comparison exercise. Comparative analysis is performed using a newly developed version of the FEEM-RICE model, a regional economy-climate model of optimal economic growth which is based on Nordhaus and Boyer’s RICE model crucially extended in order to account for induced technical change. In particular, both carbon and energy intensity are affected by a new endogenous variable – Technical Progress – which captures both the role of Learning by Researching and of Learning by Doing. These are in turn determined by the optimal levels of Research and Development and of Emission Abatement.
